Same jugs April 5th. Not everything will germinate at the same time of course. And if you keep them watered when it get warm, you can take your time to plant them out into the garden. The only jug that I lost was one of alyssum. We had an unusual cold snap for a few days the 3rd week in April and the alyssum had been up for a few weeks. The temps drops to -20ºC, which is -4ºF. It was too cold for those seedlings. The alyssum was the only one out of the 69 jugs.
